Perceptual-Motor Attributes of Mentally Retarded Youth.
Cratty, Bryant J.
To evaluate six perceptual-motor attributes of trainable and educable mentally retarded children, a battery of tests was constructed which included body perception, gross agility, balance, locomotor ability, throwing, and tracking; 83 retarded subjects provided reliability data, and their scores, with those of 120 additional subjects, provided normative data. The educable mentally retarded (EMR) and educationally handicapped (EH) groups were significantly superior in all tests to the trainable mentally retarded and Down's Syndrome groups, especially when vision and movement were paired. The Down's Syndrome group evidenced the most marked perceptual-motor deficiencies. EH children had poorer crawling and walking patterns than the EMR's, and these two groups functioned best during late childhood and early adolescence. Children with Down's Syndrome made continual improvement with increased age in tracking ability, gross agility, and in body-part perception. The majority of all subjects had difficulty making left-right identifications relative to their bodies. The correlation between IQ's and total battery scores (based on 37 IQ's) was .63 while the age to total score correlation was .54. (RJ)
